What to text when she says she's going camping with her family this weekend

A message like this is mostly logistics. She's telling you her schedule because she's a person with a family and a life, and sharing it is what people do when they're getting to know each other. The fact that she mentioned the trip at all is a small positive. People who want to disappear usually just disappear.

What she isn't saying matters too. She didn't offer a time to talk, didn't suggest anything for after, and didn't ask about your weekend. That may just be how she texts, or it may mean she's enjoying the conversation but isn't invested enough yet to plan around it. You won't know which until Monday, so don't spend the weekend building a theory.

Keep your reply about the length of hers, or a little shorter. If she gave you two sentences, send one or two. Acknowledge the camping, maybe ask one light question she can answer in a line later, and let it end. A reply that closes the topic cleanly is easier for her to respond to than one that makes her feel she owes you a plan.

Avoid turning the reply into a request. Anything that asks her to fit you in around her family, even mildly, puts her in the position of choosing between you and them for the weekend. She'll almost always choose them, and it'll feel slightly awkward for both of you.

Once you've sent your reply, don't send anything else until she does, unless something new has come up. Two messages in a row while she's away is the fastest way to look anxious. If she's offline all weekend, that's exactly what camping looks like, and it tells you nothing about how she feels.

When she's back, a short, warm message is enough, something like asking how it went. If she replies with real detail and a question back, you're fine to keep going. If she sends a brief answer and nothing else, reply briefly and see whether she opens a door. Repeated one-line replies from her after several tries are your cue to let things cool without making a point of it.
